Cosmic Knowledge and the Long-term Strategy of the Human Race

Cosmic Knowledge and the Long-term Strategy of the Human Race
Sandra Faber, UC Santa Cruz

Modern astronomy has succeeded remarkably well in explaining the cosmic origins of the human race — how the Galaxy was assembled, how the Sun and Earth were formed, and from where the precious chemical elements that comprise our bodies came. For the first time in history, the human race is poised to use that knowledge of our cosmic past to predict our cosmic future, and it looks extraordinarily bright ahead. Evidently, we human beings have been given the most precious gift of all, cosmic time — roughly a billion years of it. The ultimate challenge to our species is now clear: how will we use this extraordinary opportunity? Incorporating the profound insights from cosmology will be central to answering this question.

Zoom into the Center of Our Galaxy

This video sequence zooms into the Hubble Space Telescope view of the galactic core. Hubble’s infrared vision pierced the dusty heart of our Milky Way galaxy to reveal more than half a million stars at its core. Except for a few blue, foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest stellar cluster in our galaxy. Located 27,000 light-years away, this region is so packed with stars, it is equivalent to having a million suns crammed into the volume of space between us and our closest stellar neighbor, Alpha Centauri, 4.3 light-years away. At the very hub of our galaxy, this star cluster surrounds the Milky Way’s central supermassive black hole, which is about 4 million times the mass of our sun.

Tonight’s Sky: May 2016

Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” In May, look for galaxies embedded in the constellation Virgo.

“Tonight’s Sky” is produced by HubbleSite.org, online home of the Hubble Space Telescope. This is a recurring show, and you can find more episodes — and other astronomy videos — at HubbleSite.org.

Visit Tonight’s Sky on HubbleSite.

Zoom into the Bubble Nebula

This video starts with a backyard view of the constellation Cassiopeia and zooms into the central region of the Bubble Nebula observed by the Hubble Space Telescope.

The Bubble Nebula: Winds & Radiation from a Massive Star [Ultra HD]

Ultra HD Resolution Version (4K UHD)

This visualization of the Bubble Nebula begins with a ground-based view that encompasses the glowing cloud. The high-energy light from the massive O star, BD +60°2522, is responsible for ionizing the entire region. The virtual camera flies through the foreground stars and approaches the central bubble imaged by Hubble. The massive star continuously sheds some of its outer layers in a mass-loss wind, which has blown a bubble of gas seven light-years across. The video’s three-dimensional perspective emphasizes the extended nature of the structure and the fact that BD +60°2522 is not located at the center. The pressure inside the bubble is able to expand more rapidly in the directions away from the surrounding nebula. The computer model incorporates both scientific and artistic interpretation of the data. In particular, distances are significantly compressed.
